10/03 Hawks vs Marines

Hawks starting pitcher: Haru Matsumoto Marines starting pitcher: Yuki Karakawa

This is the second game of a two-game set at ZOZO Marine Stadium; the Hawks took the opener 4-3 yesterday. First-place SoftBank (91-47) has won seven straight, while 5th-place Lotte (61-75) has lost three in a row. The Hawks also dominate the season series 17-6, but standings and head-to-head records are already widely known and are weak grounds for calling today's game.

Haru Matsumoto starts for the Hawks. His 2.76 ERA over 117.1 innings is slightly better than his 3.20 FIP, and an 11.8% SwStr% and 30.3% CSW% show solid stuff. His last five starts produced excellent results - only five runs allowed in 29 innings - but his FIP in that span was a higher 3.64, and a 97.1% strand rate and .244 BABIP did a lot of work to keep runs off the board, so those results deserve some caution. His velocity has been steady around 145 km/h all season. He's on the road today, where he has a 3.50 ERA and 3.39 FIP over 54 innings, slightly worse results than at home but a small FIP difference.

The Marines start Yuki Karakawa, whose only top-team appearance this season was on May 30 against the Tigers (five innings, four runs, three home runs allowed), making this his first top-team outing in over four months. Five innings is almost nothing to judge by; all we know is that he averaged 148 km/h that day. He has no record against the Hawks.

Only Matsumoto has a history against today's opponent: a 3.18 ERA over three starts and 17 innings against the Marines, fine overall but with a 12.7% walk rate, higher than usual. It's a three-start sample, so context only.

Neither lineup is confirmed, so these are projections based on each team's previous game. The Hawks' offense is hot, up from a .358 season wOBA to .405 over the last five games, with a remarkable 12 home runs in that span. Kensuke Kondoh leads the way with four homers and a .700 wOBA, Yuudai Yamamoto also has four homers (.527), Yuki Yanagita is at .485 and 40-homer slugger Ryoya Kurihara at .439 - the heart of the order is rolling. Only Tomoya Masaki (.229) has cooled. The Marines, by contrast, have dropped from a .311 season wOBA to .267 (.220 average) over the last five, with Toshiya Satoh (.174) and Ryusei Ogawa (.133) struggling. 34-homer Koki Yamaguchi has two homers in that span but a below-normal .330 wOBA, and Ryusei Terachi (.389) is the best of the group. Against Matsumoto, Misho Nishikawa is 1-for-7, Satoh 1-for-6 and Ogawa 2-for-4 - small samples.

The Hawks clearly have the better bullpen too. Their relief ERA over the last ten games is 2.73 against the Marines' 5.79, with recent workloads of 7.3 innings (seven pitchers) for the Hawks and nine innings (six pitchers) for the Marines. It's 20°C at ZOZO Marine with a 0% chance of rain, but the wind is 4.5 m/s, stronger than at today's other parks.

In summary, almost every indicator - the starter, recent offensive form and the bullpen - leans toward the Hawks. The biggest variable today is how Karakawa, returning after four months, handles the early innings against a Hawks lineup that has hit 12 home runs in five games. Having allowed three homers in his only outing this season, keeping the ball in the park is the key, and an early exit would hand a lot of innings to a Marines bullpen with a 5.79 recent ERA. On the other hand, Matsumoto's recent results owe a lot to strand-rate luck, so if the Marines can build traffic with walks, this could be closer than it looks.
